SJCRAPER- SPECIFICATION forming part of Letters Patent N0. 643,314,dated. February 13, 1900. Application filed October 12. 1899. Serial No.733,376. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS W1TZMANN,a citizen of the United States,residing in New York city, borough of Manhattan, State of New York, haveinvented certain new and useful Improvements in Scrapers or Planers, ofwhich the following is a specification.

The object of my invention is to producea simple and efficient devicecapable of use in scraping brands, labels, and the like from boxes,barrels, &c., and also serviceable for scraping or planing other woodensurfaces; and the invention consists in the novel details of improvementthat will be more fully hereinafter set forth and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming parthereof, wherein- Figure 1 is a side elevation of my improvement, partlyin section, on the plane of the line a? oo'in Fig. 2. Fig. 2 is a faceview thereof, the handle being in section on the linen: in Fig. 1. Fig.3 is a detail sectional View on the line y y in Fig. 1 looking in thedirection of the arrow. Fig. 4 is a cr0ss-section on the plane of theline .2 z in Fig. 5; and Fig. 5 is a face View thereof, Figs. 4 and 5showing a form of adjustable handle.

In the accompanying drawings, in which similar numerals of referenceindicate corresponding parts in the several views, 1 indicates generallya frame which is shown provided with a bottom wall 2, having an opening3 extending transversely of the frame, an upwardly and rearwardlyinclined wall or ledge 4 extending from opening 3, and upwardly andrearwardly extending opposed sides 5, an open space being thereby formedbetween the bottom wall 2 and the sides 5. Upon the wall or ledge 1 acutting-blade 6 is adapted to rest, so that its lower cutting edge mayproject more or less through the opening 3 into the cutting position.The sides 5 are preferably provided with opposed grooves 7, in which theside edges of the blade 6 are adapted to pass,which grooves arecontiguous to the wall or ledge 4, so that the blade may rest upon thelatter. (See Figs. 1 and 1.) Upon the blade 6 rests a clamp 8, whichextends across the frame and whose side edges lie in the grooves 7, andthe upper end of the clamp 8 extends beyond the back edges of the sides5 of frame 1. At the upper corners of said clamp are located projectionsor lugs 8, which bear against the back edges 5 of sides 5, whereby thedistance that the clamp 8 can pass into the frame 1 is regulated. Inother Words, when the clamp Sis placed in the frame it is pusheddownwardly along the grooves 7 until its projections 8 abut against thesides 5, whereupon the lower edge of the clamp lies near opening 3, andthe position of the clamp 8 is thus regulated in the frame. It will beseen that the edge 8" of clamp 8 is inclined upwardly from the blade 6above the opening 3 to allow clearance for shavings or chips. The clamp8 is to be pressed firmly upon the blade (5 to hold the latter in theoperative position, and for this purpose I have provided screws 9, whichmesh in threaded bores in the sides 5 of the frame, which bores openabove the clamp 8, so that the screws 9 can bear upon the latter. Inline with the bores 10 the'clamp S is provided with counterbores orrecesses 11 to receive the ends of screws 8 to prevent the clamp frombeing shifted by the rotation of the screws while in contact therewith.

In order to enable the scraper or planer to be'conveniently and stronglymanipulated, I provide one or more handles 12 13, which are shownarranged centrally of frame 1 and connected to a cross-bar 14, that isattached to the sides 5 5 of the frame. The cross-bar 14 may be castintegral with the sides 5, as indicated in Figs. 1 and 2, and thehandles 12 13 may be removable therefrom, for which purpose thecross-bar 14 is shown provided with projections or lugs 15 16, thehandle 12 being shown connected with the projection 15 and the handle 13connected with projection 16. For this purpose handle 12 is providedwith a screw-threaded end 12 meshing in a threaded bore 15 in projection15, and handle 13 is provided with a screw-threaded end 13, meshing in athreaded bore 16 in projection 16. By this means the handles can bereadily'removed for convenience in storing and shipping the device. Itwill be seen that handle 12 projects from the planer at an acute angleto the plane ofthe rubbing-face of wall 2, which I find to be anadvantageous position for the handle, so as to afford great strength inmanipulating the device. The handle 13 is shown extending in line withthe vertical axis of frame 1, and the position of these handles is suchthat a strong downward pressure can be exerted at the same time with astrong pulling action for scraping or planing surfaces.

In Figs. 4 and 5 the support for the handles or the bar 14 is shownmovably connected with the sides 5, for which purpose it is shownswiveled on a rod or bolt 17, that passes through apertures in the sides5 and through a bore in the bar 14, and it is shown provided with a head17 at one end and a nut l7 at the opposite end for holding it securelyin the frame. The projections 15 and 16 extend from bar 14, as moreclearly shown in Fig. 4, and in order to keep the bar 14 from rotating,so that the handles 12 and 13 will be held rigidly in the operativeposition, I have provided a cross-bar 18, that rests upon the tops ofthe sides 5 and which is provided with a central aperture 18 to receivethe threaded end of handle 13. The position of projection 16 is suchthat when the threaded part 13 of handle 13 passes through aperture 18of cross -bar 18 .and meshes with threads 16 in projection 16 of bar 14the handle 12 will be rigidly held in the operative position for pullingthe scraper,

as indicated by dotted lines in Fig. 4. In some instances it may bedesirable to push the scraper or planer, and in this case the handle 13and bar 18 may be removed and the handle 12 swung over behind the frame1, as shown in full lines in Fig. 4, (the bar 14 rotating on its support17,) and to firmly lock the handle 12 in this position the bar 14 isprovided with a projection 20 on the side opposite the projection 16,the projection 20 being provided with a threaded bore 20 to receive thethreaded end 13 of handle 13, the position of projection 20 being suchthat when handle 13 is secured to the same through the cross-bar 18handle 12 will extend and be held in the proper operative position. Thecross-bar 18 is preferably rigidly connected with the sides 5 of theframe 1, and for this purpose I have shown screws 21, that pass throughapertures in cross-bar 18 and mesh in threaded bores 22 in the upperends of sides 5. (See Fig. 5.) By this means the cross-bar 18 can bereadily detached from the sides 5 to enable the handle 12 to be adjusted either to the front or back of the frame 1, and when replaced andheld by the screws 21 will serve to lock the handle 12 in either workingposition.

I do not limit my invention to the details of construction shown anddescribed, as they may be varied without departing from the spiritthereof.

Having now described my invention, what I claim is 1. In a planer orscraper, the combination of a frame having a bottom wall provided withan opening, and sides projecting above the same, a blade, means forholding the.blade in the frame, a handle-support located between saidsides and having threaded portions situated at an angleto each other,and handles for connection with said support, substantially asdescribed.

2. In a planer or scraper, the combination of a frame havingabottom wallprovided with an opening and sides projecting above the same, a blade,means for holding the blade in the frame, a bar supported between saidsides, said bar having a pair of projections extending at an angle toeach other, and handles for connection with said projections, substantially as described.

3. In a planer or scraper, the combination of a frame having a pair ofopposed sides, means for holding a blade in the frame, a handle-supportmovably connected with said sides, a bar extending across the frame inconnection with said sides, and means for securing said handle-supportto said bar, substantially as described.

4. In a planer or scraper, the combination of a frame having a pair ofopposed sides, means for holding a blade in the frame, a handie-supportmovably carried by said frame, said support having means for attaching ahandle thereto, a cross-bar to be connected with said sides, and meansfor securing the handle-support to said cross-bar,substantially asdescribed.

5.
